thanks for your response Stinkyattic, i thought i was doing a good thing using fresh rain water..... ooops. Poor plants i feel a right meany - Defo lesson learnt though.

I reverted back to tap water yesterday after reading lots of advice from off this forum hopefully they'll perk up - although was wondering whether to cull the ropey ones & just concentrate on the 3 that are ok? I'll flush them through first and see what happens over the next few days, i'm sure they'll be happier once i've done that.

Thanks so much for your help - can't bear the thought i've nearly killed them off - was only trying to be enviromentally green!!!

bye for now & thanks again
